Backyard lobster fattening unit Economic feasibility analysis

Lobsters form an important fishery all along the coastline of India. The lobster resource potential of Indian EEZ is 50,000 mt (Vijayakumaran and Radhakrishnan, 2000). Against this, lobster production of India in the year 20.00 was 2,387 t, consisting of spiny lobsters, sand lobsters, and deep-sea lobsters. While lobster fishery occurs round the year along the Indian coast and its island territories , th ere are peak seasons depending on the hydrographic conditions and natural fishery dist ribution of the regions concerned

Effect of selected chemicals on inducing relaxation in the dog conch Laevistrombus canarium (Linnaeus, 1758)

Adult dog conchs Laevistrombus canarium (60.6±1.23 mm shell length) were subjected to selected potential relaxant chemicals viz., magnesium chloride (MgCl2), magnesium sulphate (MgSO4), EDTA (ethylenediaminetetraacetic acid disodium), 2-phenoxyethanol (PE), menthol (ME) and the time taken to induce relaxation and recovery were studied. All the treatments were observed continuously for 30 min post-exposure. Among the selected relaxants, MgCl2 (30 g l-1) successfully induced adequate relaxation in 24.5 min. Relaxed conch presented an extended mantle and exhibited slow reaction to physical manipulation. Conchs exposed to all other treatments, retracted into their shells and did not show any sign of relaxation during the exposure period

Recent Nesting Record of Female Green Turtle (Chelonia mydas), at Pamban, Gulf of Mannar

A female green turtle was sighted at Pamban along the Gulf of Mannar just after the nesting on the beach on 15th January 2011. Morphometric measurements of the turtle were taken and data suggests that this individual is adult. A total number of laid eggs were 109. The distance between the nesting site and the high tide line was found to be 7 m. The depth and diameter of the nesting pit was 52 and 16 cm, whereas the mean egg diameter and weight were found to be 44.3 mm and 40.5 g respectively. Pamban coast may also be considered an important place for nesting, because of the continuous mixing of waters of GOM and Palk Bay areas, which in turn create current patterns continuously throughout the year in addition to the monsoon season. Conservation of nesting habitat along Gulf of Mannar will be important to maintain the green turtle population
